Concrete cable troughs are used to route power, signaling, communications and other cable infrastructure to
signals, relay boxes / location cases, train detection and other equipment. Cable troughs have a wide variety
of installation options and will vary from location to location. We recommend examining photos of the location
or region you are trying to duplicate in OO scale. The following photos provide some examples of cable trough
installation, all of the following photos are from the oorail photo library and are copyrighted to oorail.
The photograph above shows large capacity cable troughs (a man is standing on it) running parallel with a smaller cable trough. The large capacity cable trough looks to be either a C1.8 or C1.43 based on the height of the trough. The smaller trough is running parallel a few feet away, note the smaller trough is not running straight.
The above photograph shows three separate installations. The installation on the left and right show cable troughs running side by side in parallel at different distances from the track. Note that these examples have the cable troughs installed slightly offset so the lids are not exactly lined up. In both these installations the wider capacity cable trough runs closest to the track, while the smaller capacity runs on the outside. The installation in the middle shows a cable trough running to a colour light signal and a ground position light signal, there is also what looks to be the standard BR 'orange' cable trunking running off from the cable trough under the track to the left.
Aside from the two HSTs featured in the photo above, the location cases are installed at an eleveated height, with the cable troughs running in from the right hand side.
If you look carefully on the right hand side of this photograph, you will see a wide cable trough running along the base of the retaining wall.
This photograph shows a standard installation where the cable trough runs below the track level along the base of the track bed. In this photograph you can also see how relay boxes and other equipment are installed next to the cable trough for easy access.
In this location the track is running down hill / up hill, with steep imbankments on either side. Here the cable trough was installed several feet above the track level on the hillside. This type of installation was done to prevent water run off flooding the cable troughs and damaging the cables, as well as for easier access due to the narrow clearances due to the hillside.
This photograph shows a typical installation at a busy junction for point machines and ground position light signals.
The above location has either a C1.8 or C1.43 partially buried routed around some OHLE masts.
The photograph above shows a typical BR installation with concrete troughs of various sizes laying beside the installed concrete cable trough and the location case. Again, this installation is below the track, installed at the base of the trackbed.
This location looks like freshly installed C1.29 cable trunking, it is difficult to tell if any of the lids are installed in the distance, but the trough installed in the foreground has not had the lids or cabling installed yet.
This installation is between the tracks at a station.
In this final example, you can see new track is stacked up in preparation for installation and new cable trunking has been placed but not installed along the track.
